PAPER FEED AND CUT-OFF MEANS.

Specification of Letters Patent.

To nl] :elm/a it may Concern Be it known that I. ROBERT J. SEATOR, a citizen of the United States residing at 303 Lake avenue, Battle Creek, Michigan, have invented certain new and useful Improvements in Paper Feed and Cut-Off Means, of which the following is a specification.

This invention relates to improvements in paper feed and cut-off means.

The invention is more particularlyadapted for use in automatic wrapping machines, such as bread wrapping machines, although it is available for use in many other relations.

The objects of my invention are: First, to provide a simple, effective, adjustable malengths of paper from a roll. Second, to provide improved clutch means and mechanisms for starting and stopping the machine. Third, to provide an improved knife bladeV and means for actuating the same for such a machine. Fourth, to provide improved tension means.

' Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention bv the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

X machine which is the preferred embodiment of my invention is fully-illustrated in the accompanying drawing forming a part of this specification, in which:

ln the drawing all of the sectional views arc taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Considering the numerals of reference, I' will' state that the frame work of this machine and other parts are fully detailed and described in the concurrent application for patent relating to bread wrapping and folding machine Serial No. 781.303, filed July 26. 1018. A brief reference. however. to the parts seems necessary' in order that the paper cut-oft' and feed may be understood in this relation. and in this behalf, and so that the principles of creation involved may be clearly understood.

The main frame of the machine is supported on legs 1 1 and the frame consists of horizontal frame parts, namely, a bottom frame part 2, a top frame part 4, and an intermediate frame part 3, which supports the remaining parts. At the rear of the ma-Y wardly projecting frame 27 braced by bars 24, see Fig.v I.

The loaf shifter 90 at the top of the machine has downwardly projecting folder arms 87, 87 with folders 86 pivoted thereto at 87. These receive the loaf when it is elevated by the elevator 34, actuated by the arm 38 connected thereto by the links 35.

The carrier is driven from the shaft 15 by intermittent connection to the shaft'19. Primary end folders 97 are on a suitable carriage at the rear of the machine actuated by theV cam 107 on the shaft 11, through the connecting rod 103 which is connected to a swinging arm 105, carrying a roller 104, which coperates with the said cam 107. Secondary folders are disposed on the folder table and are coperated with by the downwardly moving end Hap folders 148. The loaf is shifted to the knotter table 153,v the loaf shifter being actuated from the roller suitable knotter.

cam 121 which is carried on shaft 121 and is actuated by suitable connections to the driv-`V ing means of the machine. The loaf is shifted laterally and the cord or twine is applied by the needle 163 which is actuated by suitable connections and coperates witha l The loaf is discharged from the table by the kicker 169 actuated by the connecting rod 169 to the lever 170,

which is pivoted to 170 and is operated by rod 171 extending to a cam 172 on shaft 78,

These parts referred to by numerals are all present in the former application and I have here identified them generally, and the full detail description will be found where the same are detailed and the matter claimed. This description is sufficient to show the relation and the purpose of these parts so far as a full understanding of the present .construction is concerned.

A trip lever 85 is pivoted on the frame at 85', see Figs. I and XVI, and connected by rod 84 to the trip :lever 83. The rod 84 and lever 83 in this relation appear distinctly in Figs. II; III, V, VI, and VII. The trip 85 is disposed to be acted on by each loaf fed into the machine. y

With this preliminary description and relation of these parts, I will now proceed to describe in detail the paper feed and cut-off mechanism constituting the parts of this present invention.

The paper roll 44 is supported on shaft 45 at the rear end of the machine on bracket 46, see Fig. I. Depending rods 47 extend down from the bracket and serve as guides for suitable bearing blocks 49, for the tension roll 48. The said tension roll plays readily up and down on the guide rods 47, and preserves an even tension upon the paper web 43. Paper web 43 is looped downwardly around the tension roll 48-and then upwardly to a pair of feed rolls 50-52. Feed roll 50 is supported on the shaft 51 and the feed roll 52 is supported on the shaft 53, which is in the vertically movable bearing blocks '176 which are. adjustable, and play freely up and down in ways 177 at each end thereof. Springs 178 put tension upon the bearing blocks so that the grasp of the rolls is sutiicient to feed and deliver the paper to the cut-ofi' means. The shaft 51 and feed roll 50 are actuated intermittently and constitute the driven roll of this feed mechanism.

The clutch fork 82 is carried by the lever 201, which is pivoted at 203, see Fig. V. Said lever 201 has an actuating pin 202 at its forward end. y'The clutch fork 82 engages in an annular groove 204 on the hub of gear 187. Clutch teeth 205 are on thc opposite face of gear 187, and correspond -with and engage teeth 206 on the face of the disk or pulley 208, on which is the chain brake 207. The chain brake 207 is connected to arm 199 by pivot 210, and the opposite end is secured by pin 209 to the frame 175. The frame 175 supporting and carrying these parts of the paper feed is secured to the rear end of the machine about the end plate 5.

The gear 187 is driven by the gear 186 on shaft 185. The shaft 185 is driven by the gear 184 secured thereto which meshes with the gear 183 on the shaft 78. The shaft 78 is driven by the sprocket chain 80, which is driven from the shaft 15 on the frame of the machine, on which is keyed the sprocket wheel 81. See Figs. I and III. It will therefore be seen that the paper feed runs at comparatively high speed, so that a very short interval only is required to deliver the proper amount of paper to the machine.

Paper knife 69 is disposed to descend into a slot in the block 69', over which the paper is delivered into suitable guides 43". The knife 69 is serrated, as seen in Fig. X, and is carried on the transverse bar 70. The bar 70 is supported on the side frames 175, 175 on vertical guide rods 76 on which it reciprocates. The bar 70 is urged downwardly by coiled springs 76 on the guide rod 76 at each end thereof, see Figs. V, X and XI.

Onrock shaft 74 are secured a pair of arms 73, the rear ends of which are connected by links 71 to the knife bar 70, the links being pivoted at 72. An arm 75 is secured to the rock shaft 74, and a roller Lwaaae 75 is disposed in a fork at the end thereof to-coperate with the cam 77 which is carried and actuated bythe shaft 78. The shaft 78. is supported in the side frames 175, 175 already referred to. The cam 77 is made adjustable by the relatively-adjustable part 179, which is keyed to the shaft 78. The ad-` justment isl accomplished by means of the hand-nut 182 on the screw-threaded end of the'shaft78. The cam 77 has a pin 181 which is adapted to fit any one of the series of holes 180 inthe part 179, and by this means the length of the cam and the distance of the feed of the paper can be regulated and the timing of the action of the knife completely and effectively controlled.

The shaft 78 is, of course, intermittently controlled. On rock shaft 74 is also secured arm 188, havingthe trip block 189, see Fig. V11, for throwing the entire paper feed and cut-off mechanism into and out of gear.

This arm 188 is provided with the yielding elevating` spring 188 to throw the same upwardly whenever itv is released, said spring resting .upon the periphery of the spur gear 183.

' The projecting trip block 189 acts upon the dog lever 190, which is pivoted at 191 on the face of the gear 183, and is held yieldingly in position by the coiled spring 192. Lever 190 is pivoted on the face of the sprocket gear 79 and is held yieldingly in engaging position by the coiled spring 192 connected at one end to the said lever and to the other end by pin 193 on the said sprocket gear 79. The lever 190 is provided with a dog 191 which engages with the dog block or lug 195 on the face of the spur gear 183. 1t will thus be seen that whenever the trip block 189 is elevated or thrown upwardly, it permits the dog 191 to move outwardly into engagement with'the lug 195 and thereby actuate the gear 183. The lever 83 is actuated by the connection 81 already referred to: This lever is urged rearwardly by spring 196, and is provided with an engaging pin 197, see particularly Fig. V. A projecting finger 198 is on the hub of the arm 188, disposed to be engaged by the pin 197. lt will thus be seen that when the rod 81 is pulled that it will carry the lever 83 and pin'197 out from under the finger 198, which will permit the arm 188 to swing upwardly by the action of the spring 188', and the trip block 189 will then beelevated and permit the dog 191 to act. This will cause the gear 183 to rotate and control the shaft 78, which will, of course, actuate the cam 77 which acts upon the roller which, through the arm 75, controls the shaft 74. When the paper is cut 0H by the action of this cam, the trip block 189 will be forcibly carried down and immediately locked in position by the pin 197 engaging under the finger 198 and will, when the dog 194 swings around, cause the same to be depressed out of engagement, thereby throwing the structure one of gear and preventing its further operation. The arm 199 is also secured to the rock shaft 74, and depends downwardly therefrom and carries the pin 210 towhich the brake chain 207 is secured so that when the paper is cut off the brake is immediately applied and the feed rolls stopped. On the side of this lever 199 is also a wedge or cam 200 which is disposed and arranged to act upon the downwardly-extending pin 202 on the end of arm 201, 'which shifts the lever 201 and throws out the clutch for driving the\shaft 51.

From this detailed description, the entire operation of my improved paper feed and cut-off is very clear. To recapitulate, When the loaf on the loaf feed carrier strikes the trip lever 85, see Fig. XVI, it pulls the rod 84 and actuates the trip lever 83. This throws the pin 197 out from under the finger 198, and the spring 188 throws the lever 188 upwardly, carrying the trip block 189 up and permits the dog 191 to swing outwardly by the Iaction of the dog lever 190. This permits the dog 190 to engage the lug 195 see Figs. 111 and V111 and enables the sprocket wheel 79 to drive the gear 183, and this drives the shaft 78. The gear 183 meshing with the pinion 181e on the shaft 185 drives the gear 186 which meshes with the gear 187, which, through the clutch connection, drives the feed roll shaft 51, the clutch on which is controlled by the lever 201 actuated by the cam on arm 199 on the rock shaft 74, so that it will be seen that whenever the lever 83 is tripped the feed mechanism and cut-off mechanism starts and completes an evolution. The length of the paper fed is controlled by the length of the enlarged part of the cam 77. Also this cam 77 is the trip means for throwing other parts of a mechanism into operation and secures coperation between other parts of the folder and the paper feed and cut-off, so that the balance of the mechanism is only put into operation after the paper has been properly fed and cut off.

I have shown in my improved paper feed and cut-off the specific form which I consider most desirable, and 1 desire to claim same in the specific form, and 1 also desire to claim the same broadly as in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
